How Much Water You Should Drink Before, During, and After Exercise

Stay Rehrdated

Staying hydrated is essential for your health, particularly when you're working out and possibly losing a lot of water through sweat. This infographic from Greatist and CamelBak take the mystery out of how much water you need to drink, depending on the kind of exercise you do and other factors.

You can live without food for about a month, but only without water for a week. As the graphic points out, general guidelines are to drink 17 to 20 ounces of water 2 to 3 hours before exercising, another 8 ounces during your warm-up (or 20 to 30 minutes before exercising), 7 to 10 ounces every 10 to 20 minutes during exercise, and 8 ounces of water within 30 minutes after exercising. Yes, that's a lot of water!

How much you need to drink, however, depends on your age, gender, height, weight, exercise intensity, and how long you exercise. People who sweat a lot may need to drink more. The graphic includes example water amounts for men and women and several other hydration tips.
